Systematic Parasitology (Syst Parasitol)
Systematic Parasitology publishes papers on the systematics taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic) Monogenea Digenea Cestoda Acanthocephala Aspidogastrea Cestodaria Arthropoda (parasitic copepods hymenopterans mites ticks etc.) Protozoa (parasitic groups) and parasitic genera in other groups such as Mollusca Turbelleria etc. Systematic Parasitology publishes fully illustrated research papers brief communications and fully illustrated major revisions. In order to maintain high standards all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that in some cases this may cause problems for the authors but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa and the types will be preserved for posterity.

Article: Three species of opisthomonorchiine monorchiids (Digenea) in Carangoides spp. (Perciformes: Carangidae) from off New Caledonia, with a description of Opisthomonorchis dinema n. sp.[show abstract] [hide abstract]
ABSTRACT: Three opisthomonorchiinae species are described from fishes obtained at the Fish Market in Nouméa, New Caledonia. Opisthomonorchis dinema n. sp. from Carangoides dinema Bleeker differs from the other recognised species in the genus by the long recurved genital atrium, arcing anteriorly. Also described are Opisthomonorchis carangis Yamaguti, 1952 from Carangoides sp. and Pseudopisthomonorchis thapari (Varma & Singh, 1979) n. comb. for Opisthomonorchis thapari Varma & Singh, 1979 from Carangoides chrysophrys (Cuvier). The features distinguishing Opisthomonorchis Yamaguti, 1952 and Pseudopisthomonorchis Madhavi, 1974 are discussed.Systematic Parasitology 06/2013; 85(2):147-156.
Article: New data on Longidorus aetnaeus Roca, Lamberti, Agostinelli & Vinciguerra, 1986 (Nematoda: Longidoridae) from Iran and Ajaria (Georgia).[show abstract] [hide abstract]
ABSTRACT: Longidorus aetnaeus Roca, Lamberti, Agostinelli & Vinciguerra, 1986 is reported for the first time from Iran and Ajaria (Georgia). Morphological and morphometric data are provided for two Iranian and one Ajarian populations. The D2-D3 region of 28S rDNA for both Iranian populations was sequenced for the first time and the data reported. A detailed study of juveniles of L. aetnaeus from Iran, Georgia and Bulgaria demonstrated that this species develops through three juvenile stages. Furthermore, phylogenetic studies inferred from sequences for the D2-D3 region of 28S rRNA gene revealed that L. aetnaeus is most closely related to L. leptocephalus.Systematic Parasitology 06/2013; 85(2):173-187.
Article: Redescription of Eimeria zarudnyi Alyousif & Al-Shawa, 2003 as Choleoeimeria zarudnyi n. comb. (Apicomplexa: Eimeriidae).[show abstract] [hide abstract]
ABSTRACT: Coprological examination of the worm lizard Diplometopon zarudnyi Nikolskii revealed the presence of oöcysts of Choleoeimeria zarudnyi (Alyousif & Al-Shawa, 2003) n. comb. in five (17%) of the 30 lizards examined. Sporulated oöcysts were found in the faeces and the gallbladder contents. These are tetrasporocystic, ellipsoidal, 25-32 × 18-25 (mean 27 × 22) μm, with a smooth bi-layered wall. The dizoic sporocysts are ovoidal, 10-13 × 6-9 (mean 11 × 7) μm, with a granulated sporocyst residuum. Sporozoites are banana-shaped with an average size of 13 × 3 μm. Endogenous stages (meronts, gamonts and gametes) are confined to the gallbladder epithelium and the infected cells were hypertrophied. Based on the morphological features of the exogenous stages and the endogenous development of the present parasite, its generic affiliation is revised and Eimeria zarudnyi Alyousif & Al-Shawa, 2003 is transferred to the genus Choleoeimeria.Systematic Parasitology 06/2013; 85(2):189-194.
Article: A new species of Caryospora Léger, 1904 (Apicomplexa: Eimeriidae) from the snake Philodryas olfersii Lichtenstein (Colubridae) from a coastal habitat in Brazil.[show abstract] [hide abstract]
ABSTRACT: A new coccidian species of the genus Caryospora Léger, 1904 (Protozoa, Apicomplexa, Eimeriidae) is reported from the colubrid snake host Philodryas olfersii Lichtenstein at a coastal area in the State of Rio de Janeiro, south-eastern Brazil. Oöcysts of Caryospora olfersii n. sp. are spherical to sub-spherical, 33.1 × 31.2 μm, with smooth, colourless, three-layered wall, c.1.4; middle layer lightly striated. Micropyle, oöcyst residuum and polar granule are all absent. Sporocysts are ovoid, 22.9 × 17.4 μm on average, with one extremity in the shape of a short neck. Stieda body present, 3.2 × 1.3 μm, sub-Stieda body present, homogeneous, larger than Stieda body, 4.5 × 1.7 μm. Sporozoites are inserted in a bulky sporocyst residuum.Systematic Parasitology 06/2013; 85(2):195-199.
Article: New species of Kiluluma Skrjabin, 1916 (Nematoda: Strongylida) from the white rhinoceros Ceratotherium simium (Burchell), with a redescription of K. solitaria Thapar, 1924.[show abstract] [hide abstract]
ABSTRACT: Three species of Kiluluma Skrjabin, 1916 were identified in Ceratotherium simium (Burchell) from a captive population in New South Wales, Australia, based on analysis of the second internal transcribed spacer (ITS-2) of ribosomal DNA. One species was identified as K. solitaria Thapar, 1924 and is redescribed. A second species is new and is described here as K. ceratotherii n. sp. The third species is new but was represented by two individuals only and is described but is not named.Systematic Parasitology 06/2013; 85(2):131-145.
Article: Morphological and molecular characterisation of Xiphinema macroacanthum Lamberti, Roca & Agostinelli, 1989 (Nematoda: Longidoridae) from olive orchards in southern Italy.[show abstract] [hide abstract]
ABSTRACT: A population of Xiphinema macroacanthum Lamberti, Roca & Agostinelli, 1989 originating from olive orchards in Brindisi, Italy and containing both adults and all juvenile stages, is described and illustrated. The first juvenile stage is reported for the first time. Molecular characterisation of this species, using the D2-D3 expansion domains of the 28S rDNA and ITS region, was carried out. PCR-RFLP analyses of the ribosomal gene regions determined species-specific patterns that clearly differentiate X. macroacanthum. Sequences of the D2-D3 domains and the partial 18S-ITS1 rRNA genes were analysed using several methods for inferring phylogeny to reconstruct the relationships between X. macroacanthum and other Xiphinema species.Systematic Parasitology 06/2013; 85(2):157-171.
Article: Ligophorus abditus n. sp. (Monogenea: Ancyrocephalidae) and other species of Ligophorus Euzet & Suriano, 1977 infecting the flathead grey mullet Mugil cephalus L. in the Sea of Japan and the Yellow Sea.[show abstract] [hide abstract]
ABSTRACT: As a result of the re-examination of museum slides and new material of monogeneans collected from Mugil cephalus L. in the Sea of Japan, the estuary of a river which flows into the Sea of Japan, the Yellow Sea (off Zhifu, at the boundary of the Bohai Sea) and the East China Sea (off the Ryukyu Islands), five species of Ligophorus Euzet & Suriano, 1977 were identified, one of which is new. The known species are L. chabaudi Euzet & Suriano, 1977, L. cheleus Rubtsova, Balbuena & Sarabeev, 2007, L. domnichi Rubtsova, Balbuena & Sarabeev, 2007 and L. pacificus Rubtsova, Balbuena & Sarabeev, 2007, which are reported from the Yellow Sea; in addition, L. domnichi is reported for the first time from the East China Sea. Ligophorus abditus n. sp., from the Sea of Japan, differs from its most similar congeners, L. pacificus and L. domnichi, in the shapes of the dorsal anchors and the accessory piece of the male copulatory organ. A comparison of all of the species of Ligophorus recovered from M. cephalus in the Sea of Japan was carried out using Principal Component Analysis, and their distribution and origin are discussed.Systematic Parasitology 06/2013; 85(2):117-130.
Article: A new species of Grillotia Guiart, 1927 (Cestoda: Trypanorhyncha) with redescriptions of congeners and new synonyms.[show abstract] [hide abstract]
ABSTRACT: A new species of Grillotia, G. gastrica n. sp., is described from the stomach musculature of the teleosts Upeneichthys lineatus (Bloch & Schneider) and Sillaginodes punctatus (Cuvier) from off Perth, Western Australia. The new species most closely resembles G. pristiophori Beveridge & Campbell, 2001 in having six hooks in each principal row of the metabasal tentacular armature but differs in having a smooth scolex tegument and in having a band of hooklets running the entire length of the external surface of the tentacle rather than diminishing in width to a single hooklet as occurs in G. pristiophori. Grillotia heptanchi (Vaullegeard, 1899) is redescribed and the details of the mature segment are described for the first time. Grillotia adenoplusius (Pintner, 1903) is redescribed from the type-specimens and is considered to be the larval stage of G. acanthoscolex Rees, 1944 (syns G. spinosissima Dollfus, 1969 and G. microthrix Dollfus, 1969). The adult of G. adenoplusius is also redescribed based on the types of G. spinosissima. The type-specimens of G. dolichocephala Guiart, 1935 and G. minor Guiart, 1935 were re-examined and G. minor is considered to be a synonym of G. dolichocephala as is G. meteori Palm & Schröder, 2001. Based on an examination of the type-specimens, G. scolecina (Rudolphi, 1819) is treated as a species inquirenda. A list is provided of the species currently placed in Grillotia.Systematic Parasitology 06/2013; 85(2):99-116.
Article: Morphometric and molecular characterization of the species of Uncinaria Frölich, 1789 (Nematoda) parasitic in the Australian fur seal Arctocephalus pusillus doriferus (Schreber), with notes on hookworms in three other pinniped hosts.[show abstract] [hide abstract]
ABSTRACT: This study presents morphological and molecular data on hookworms from the Australian fur seal Arctocephalus pusillus doriferus (Schreber) currently identified in Australian waters as Uncinaria hamiltoni Baylis, 1933. Additional specimens from the Australian sea lion Neophoca cinerea (Péron) and the New Zealand fur seal Arctocephalus forsteri (Lesson) from Australia, and the Southern elephant seal Mirounga leonina (Linnaeus) from Antarctica, were included. Using the internal transcribed spacer (ITS), hookworms from A. p. doriferus, N. cinerea and A. forsteri were found to be genetically similar but distinct from Uncinaria spp. found in M. leonina from Antarctica, as well as from Zalophus californianus (Lesson) and Callorhinus ursinus (Linnaeus) from California. Few morphological differences were detected between these taxa.Systematic Parasitology 05/2013; 85(1):65-78.
Article: Poecilorhynchus perplexus n. g., n. sp. (Trypanorhyncha: Eutetrarhynchidae) from the brownbanded bambooshark, Chiloscyllium punctatum Müller & Henle, from Australia.[show abstract] [hide abstract]
ABSTRACT: A new genus of trypanorhynch cestodes is described from the brownbanded bambooshark, Chiloscyllium punctatum Müller & Henle (Hemiscylliidae) from off Nickol Bay, Western Australia. Poecilorhynchus perplexus n. g., n. sp. is placed in the Eutetrarhynchidae Guiart, 1927 because it is characterised by an elongate, acraspedote scolex with two oval bothria, the absence of bothrial pits, elongate bulbs, the presence of gland-cells within the bulbs and prebulbar organs, retractor muscles inserting at the base of each bulb and an acraspedote strobila. It can be distinguished from all other genera in this family by its possession of a poeciloacanthous typical armature, with a chainette composed of two longitudinal files of uncinate hooks on the external tentacular surface.Systematic Parasitology 05/2013; 85(1):1-9.
Article: Two new species and a new phyllobothriid cestode genus from sharks of the genus Negaprion Whitley (Carcharhiniformes).[show abstract] [hide abstract]
ABSTRACT: Alexandercestus n. g. (Cestoda: Tetraphyllidea) is erected for two cestode species found parasitising the two known species of lemon sharks (Carcharhiniformes: Negaprion spp.). This new genus differs from all other phyllobothriid genera except for Hemipristicola Cutmore, Theiss, Bennett & Cribb, 2011, Marsupiobothrium Yamaguti, 1952, Nandocestus Reyda, 2008, Orectolobicestus Ruhnke, Caira & Carpenter 2006, Orygmatobothrium Diesing, 1863, Paraorygmatobothrium Ruhnke, 1994 and Phyllobothrium van Beneden, 1849 in possessing uniloculate bothridia with an apical sucker and neck scutes. Alexandercestus differs from Orectolobicestus and Nandocestus in lacking marginal loculi on the bothridia, from Paraorygmatobothrium in possessing uninterrupted vitelline follicles at the level of the ovary and from Phyllobothrium in being euapolytic as opposed to anapolytic and in lacking posteriorly bifid bothridia. The new genus lacks the central accessory bothridial organ seen in specimens of Orygmatobothrium, and lacks the central bothridial accessory sucker of specimens of Marsupiobothrium. Alexandercestus spp. compare most favourably with specimens of Hemipristicola, especially with respect to aspects of proglottid morphology, but differ in possessing aristate gladiate spinitriches rather than serrate gladiate spinitriches on the proximal bothridial surface. In addition, the bothridia of Alexandercestus spp. are comparatively more fleshy and foliose than those in specimens of Hemipristicola. Two new species of Alexandercestus n. g. are described, Alexandercestus gibsoni n. sp. from Negaprion acutidens, collected from off northern Australia and the Marshall Islands, and Alexandercestus manteri n. sp. from N. brevirostris, collected off the islands of Bimini and the Florida Keys. The two new species differ in total length and vitelline follicle distribution. Bayesian inference and parsimony analysis of the D1-D3 region of the large nuclear ribosomal DNA of 17 published and seven novel sequences placed A. gibsoni as the sister taxon to a clade containing Hemipristicola gunterae Cutmore, Theiss, Bennett & Cribb, 2011 and species of Paraorygmatobothrium. This result supports the erection of Alexandercestus as a genus separate from Hemipristicola and Paraorygmatobothrium. At the present time, species of Alexandercestus are known only from hosts of the carcharhinid genus Negaprion Whitley; examination of extensive survey data suggests this may be the extent of the host distribution of this genus.Systematic Parasitology 05/2013; 85(1):37-48.
Article: The morphology and systematics of Rhabdochona paski Baylis, 1928 (Nematoda: Rhabdochonidae), a widespread parasite of freshwater fishes in Africa.[show abstract] [hide abstract]
ABSTRACT: Nematodes of the genus Rhabdochona Railliet, 1916, identified as R. paski Baylis, 1928, were collected from the intestine of Hydrocynus forskahlii (Cuvier) (Characiformes: Alestidae), Oreochromis niloticus (Linnaeus) and Tilapia zillii (Gervais) (both Perciformes: Cichlidae) from Lake Turkana, Kenya during 2007-2009. Their morphology was studied in detail using light and scanning electron microscopy. Paratypes of R. paski and museum specimens of R. congolensis Campana-Rouget, 1961 from six other host species were examined for comparison. Based on these studies and the available literature data, Rhabdochona congolensis, R. aegyptiaca El-Nafar & Saoud, 1974 (emend.) and R. vesterae Boomker & Petter, 1993 are considered to be junior synonyms of R. paski. The occurrence of this widely distributed African nematode in many fish species belonging to different families and orders suggests that most of them are probably not definitive hosts of this parasite, but only serve as paratenic, paradefinitive or postcyclic hosts (sensu Odening, 1976). True definitive hosts of R. paski appear to be characiform species belonging to some genera (e.g., Alestes, Brycinus, Hydrocynus) of the family Alestidae.Systematic Parasitology 05/2013; 85(1):55-63.
Article: Isospora canaria Box, 1975 (Apicomplexa: Eimeriidae) from canaries Serinus canaria Linnaeus (Passeriformes: Fringillidae) in Brazil.[show abstract] [hide abstract]
ABSTRACT: Isospora canaria Box, 1975 (Protozoa, Apicomplexa, Eimeriidae) is reported and described from canaries Serinus canaria (Linnaeus) in southeast Brazil. Its oöcysts are subspheroidal to ellipsoidal, 24.4 × 22.2 μm, with smooth, bilayered wall, ~1.2 μm. The micropyle and the oöcyst residuum are absent, but a polar granule is present. The sporocysts are lemon-shaped, 17.6 × 10.6 μm. The Stieda body is nipple-like, and substieda body is prominent and homogeneous. The sporocyst residuum is composed of scattered granules. The sporozoite has anterior and posterior refractile bodies and a nucleus. The report of this coccidium recovered from exotic canaries in South America is relevant to native passerines, mainly to Carduelis yarrellii, which are listed as vulnerable species by IUCN (International Union for Conservation of Nature and Natural Resources).Systematic Parasitology 05/2013; 85(1):49-53.
Article: Two new species of Pupulina van Beneden, 1892 (Copepoda: Siphonostomatoida: Caligidae) from mobulid rays off South Africa.[show abstract] [hide abstract]
ABSTRACT: The caligid genus Pupulina van Beneden, 1892 currently has three accepted species. Two new species, Pupulina cliffi n. sp. and P. merira n. sp., are described from Mobula kuhlii (Müller & Henle) and M. eregoodootenkee (Bleeker) (Mobulidae) caught along the east coast of South Africa. Pupulina cliffi can be distinguished from all the other species by the absence of posterolateral processes on the genital complex, whereas P. merira has very short, rounded posterolateral processes on the genital complex compared to the three previously known species. Additionally, P. merira is the only species with the abdomen only about two-thirds the length of the genital complex and the caudal rami about the same length as the abdomen. A dichotomous key to distinguish the five species of Pupulina is provided.Systematic Parasitology 05/2013; 85(1):27-35.
Article: New records and descriptions of digeneans from the Magellanic penguin Spheniscus magellanicus (Forster) (Aves: Sphenisciformes) on the coast of Brazil.[show abstract] [hide abstract]
ABSTRACT: Five species of digeneans parasitic in the Magellanic penguin Spheniscus magellanicus (Forster) from off the Brazilian coast of the western Atlantic are reported for the first time from this host and described. These are Mesostephanus odhneri (Travassos, 1924) Lutz, 1935, Posthodiplostomum macrocotyle Dubois, 1937, Stephanoprora uruguayensis Holcman-Spector & Olagüe, 1989, Ascocotyle (Phagicola) longa Ransom, 1920 and Ascocotyle (Phagicola) sp. One other digenean, Cardiocephaloides physalis (Lutz, 1926) Sudarikov, 1959, was also recorded. The taxonomy of the species and available data on their life-cycles are commented upon in relation to the possible origins of digenean infections of the Magellanic penguin.Systematic Parasitology 05/2013; 85(1):79-98.
Article: Morphological and molecular differentiation of two new species of Pseudoacanthocephalus Petrochenko, 1958 (Acanthocephala: Echinorhynchidae) from amphibians and reptiles in the Philippines, with identification key for the genus.[show abstract] [hide abstract]
ABSTRACT: The genus Pseudoacanthocephalus Petrochenko, 1958 currently includes 14 species of acanthocephalans parasitic in amphibians and reptiles worldwide. This work describes two new species of Pseudoacanthocephalus from amphibians and reptiles collected in several localities on Luzon Island, Philippines. Pseudoacanthocephalus nickoli n. sp. was found in two species of frogs, Rana luzonensis Boulenger and Rana similis (Günther), and Pseudoacanthocephalus smalesi n. sp. was found in a scincid lizard, Sphenomorphus abdictus Brown & Alcala. Differential diagnoses of the two new species of Pseudoacanthocephalus from their congeners are provided. Comparative analysis of nuclear ribosomal rRNA sequences encompassing the 3' end of 18S nuclear rDNA gene, internal transcribed spacer region (ITS1+5.8S+ITS2), and 5' end of the 28S gene strongly corroborated the morphological evidence and demonstrated significant differences between the two new species as well as between these species and closely related species from continental China and Vietnam. No intraspecific sequence variability was detected among different individuals representing each of the examined species. This is the first report of Pseudoacanthocephalus in the Philippines. A key to known species of Pseudoacanthocephalus is provided.Systematic Parasitology 05/2013; 85(1):11-26.
Article: Intra-specific variation of Kudoa spp. (Myxosporea: Multivalvulida) from apogonid fishes (Perciformes), including the description of two new species, K. cheilodipteri n. sp. and K. cookii n. sp., from Australian waters.[show abstract] [hide abstract]
ABSTRACT: Kudoa spp. from the musculature and intestinal mucosa of species of the teleost family Apogonidae were examined for their taxonomic identity. Two novel species are characterised: Kudoa cheilodipteri n. sp. from the musculature of Cheilodipterus quinquelineatus Cuvier, Ostorhinchus cyanosoma (Bleeker) and O. aureus (Lacépède); and Kudoa cookii n. sp. from the submucosa of the intestines of O. cookii (Macleay) only. Both species are characterised using morphology, small subunit ribosomal DNA (SSU rDNA), large subunit ribosomal DNA (LSU rDNA), and biological characters. Three new host records, O. cyanosoma, O. aureus and Apogon doederleini, and associated geographical, morphological and genetic data are also provided for Kudoa whippsi Burger & Adlard, 2010. Morphological and molecular intra-specific variation of all isolates assigned to K. whippsi is also examined. Phylogenetic analyses further support the idea that tissue tropism is a distinguishing character between morphologically similar species; species reported here display close relatedness to morphologically similar species infecting the same tissue within their hosts.Systematic Parasitology 03/2013; 84(3):193-215.
Article: Further studies on Contracaecum spasskii Mozgovoi, 1950 and C. rudolphii Hartwich, 1964 (sensu lato) (Ascaridida: Anisakidae) from piscivorous birds in China.[show abstract] [hide abstract]
ABSTRACT: Contracaecum spasskii Mozgovoi, 1950, collected from the great crested grebe Podiceps cristatus (Linnaeus) (Podicipediformes: Podicipedidae), is redescribed using both light and, for the first time, scanning electron microscopy. Contracaecum spasskii differs from its congeners by having marked transverse cuticular annulations, the length of the oesophagus and spicules, the ratio between the intestinal caecum and the ventricular appendix, the number and arrangement of male caudal papillae, and especially by the particular morphology of the lips and interlabia. Some previously unreported morphological features of C. spasskii are also revealed and others corrected. Contracaecum rudolphii Hartwich, 1964 (sensu lato) is also redescribed based on the specimens collected from the great cormorant Phalacrocorax carbo sinensis (Blumenbach) (Pelecaniformes: Phalacrocoracidae) from China. Based on the geographical perspective, the present Chinese material may represent the species C. rudolphii B.Systematic Parasitology 03/2013; 84(3):225-36.

ABSTRACT: The Opecoelidae (Digenea) of eight species of goatfishes (Perciformes: Mullidae) were studied off Lizard Island on the northern Great Barrier Reef (GBR). Host species included Mulloidichthys flavolineatus (Lacépède), M. vanicolensis (Valenciennes), Parupeneus barberinus (Lacépède), P. ciliatus (Lacépède), P. cyclostomus (Lacépède), P. indicus (Shaw), P. multifasciatus (Quoy & Gaimard), P. spilurus (Bleeker) and P. trifasciatus (Lacépède). Seven opecoelid species were found, of which Paropecoelus corneliae n. sp., Pa. leonae n. sp. and Pseudopecoeloides engeleri n. sp. are described as new. Paropecoelus elongatus (Ozaki, 1928), Pa. sogandaresi Pritchard, 1966 and Podocotyloides parupenei (Manter, 1963) are recorded and a description is provided for each. A second species of Pseudopecoeloides remains unnamed for want of sufficient morphological material. The seven species were distinguished on the basis of morphology and molecular analysis of 56 ITS2 rDNA sequences. Sequences differed by nine to 68 base pairs between species combinations recognised by morphology; no intraspecific variation was detected. Each opecoelid species infected between two and five mullid species, but none of the species has been found in non-mullid hosts. Every mullid species was infected with at least one species of opecoelid and Parupeneus ciliatus had all seven species. The Opecoelidae of GBR goatfishes are consistent with the typical pattern of stenoxenicity seen for trematodes of GBR fishes.Systematic Parasitology 03/2013; 84(3):237-53.
Article: A new species of Procolobomatus Castro Romero, 1994 (Copepoda: Philichthyidae) endoparasitic in a deepwater longtail red snapper (Actinopterygii: Lutjanidae) off Ishigaki Island, Japan, with records of philichthyid copepods reported from Asian waters.[show abstract] [hide abstract]
ABSTRACT: A new species of the Philichthyidae Vogt, 1877 (Copepoda: Poecilostomatoida), Procolobomatus hoi n. sp., is described based on adult female specimens recovered from the cephalic sensory canals of Etelis coruscans Valenciennes (Actinopterygii: Lutjanidae) caught off Ishigaki Island, the Ryukyu Islands, southern Japan. The new species differs from its congeners by having the following combination of characters: a long medial cephalic lobe about one-third the length of the body; an armature of five spines on the distal exopodal segment of leg 2; one long apical seta on the papillose leg 4; a caudal ramus armed with one medial and four terminal setae (two middle setae are inflated); and spinulose ornamentation covering the body. Procolobomatus hoi n. sp. is the first member of the genus reported from the western Pacific Ocean and from a host of the family Lutjanidae. Previous records of philichthyid copepods from Asian waters are also reported.Systematic Parasitology 03/2013; 84(3):217-24.
